That is cool Martin! The only thing I'd probably try is doing a NOT gate with
just a lever, like a 3L liftarm. May reduce backlash a little.
It would be interesting to investigate a way to make them with a +V input of
some kind - maybe a motor somehow - that does the switching of the output,
similar to the compressor input of the pneumatic models. If that could be done,
it might make much larger circuits viable.
